I don't know what you mean about a splitter, unless you are saying to divide into a wet and dry signal to keep a little of the original low-end in the signal. My solution to the lack of lows from the Big Muff is to keep a seperate Boss EQ in the line right behind it, dedicated just for use with the Big Muff, with a low and low-mid boost.

well i got a splitter for my tv's so its like best buy (you know the feeling while walking through the TV section with the TV's on the same channel)but only with 2 tv's i plan on adding more for that "buest buy look" if i can find some more TV's in the garbage down my block.
